Book Description
A dozen papers from a December 1993 symposium in Dallas/Fort Worth, Texas. Among the topics are why the new proposed rheological properties of asphalt binders are required and how they compare to conventional properties, the development and use of the SHRP direct tension specification test, oxidatio

Book Description
Results of usual tests for specification compliance and special tests to show viscosity-temperature susceptibility and ductility penetration relationships for asphalts supplied for use by the Virginia Department of Highways and Transportation in 1983 are reported. The results to date have not revealed any asphalts with unusual properties. Differences in viscosity-temperature susceptibilities of products from different suppliers were relatively small. The results also indicate that satisfactory performance of properly designed and placed mixtures would be expected with all of these products, but a firm conclusion to this affect cannot be drawn until the ability of the asphalts to adhere to aggregates is determined. Such tests are planned. The addition of a requirement to asphalt cement specifications that the ash not exceed 0.40 percent is recommended. Such a requirement would provide protection against products from unusual refining processes that contain appreciable amounts of organic sodium salts.

Book Description
Detailed data were collected from field and laboratory evaluations to determine whether changes in crude oils affect the physical and chemical properties of asphalt binders over time. The test results indicated that asphalt cement properties produced today have the same range of values as those produced in the 1990s. Asphalts with high-viscosity susceptibility were shown to be associated with pavement distress. Field evaluations showed that asphalts with a viscosity susceptibility value lower than 0.088 will perform well without premature failure. Asphalts containing relatively low asphaltenes, particularly those of softer grade, appeared to have a greater probability of producing mixtures that could lead to pavement distress. Data analyses revealed that a good knowledge of the physical characteristics and chemical composition of asphalts can provide a useful tool for distinguishing between asphalts associated with pavement performance.

Book Description
This final report, in four volumes, of Strategic Highway Research Program (SHRP) Project A-002A describes intensive investigations of the chemical and physical properties of petroleum asphalts used in the construction of highway pavements. The model and predictive capability constitute the major portion of volume 1.
